Electron screening in Titanium

Abstract

Abstract Electron screening is very important in nuclear astrophysics. For nucleosynthesis calculations precise reaction rates should be known at very low energies, where screening cannot be neglected. Despite its importance, a huge disagreement between experimental data and theoretical predictions is still not explained. Recently, we studied the electron screening effect in deuterium implanted titanium targets by measuring the γ-ray yield produced from the 19F(d,p)20F nuclear reaction in inverse kinematics. Our preliminary results are presented below.
